Friends and former Bruins teammates Bobby Orr and Derek Sanderson had a few laughs at an event hosted this week by Baystate Wealth Management. (Sanderson is heading up a new division of BWM focused on investment services for professional athletes.) “Turk,” as Sanderson was known in his playing days, has written a memoir, “Crossing the Line,” and is the subject of a biopic being produced by Ed Burns. Asked about the state of the National Hockey League these days, he had this to say: “Some of the franchises are struggling. Get rid of the weak franchises and you’ll have a deeper, more talented league.” We’d be satisfied if they just played a game or two. . . . There was a Daisuke Matsuzaka sighting Thursday.
